"High quality custom designed black anodized cases with enough room to upgrade the amp to a 4-channel balanced amp in the future." Not going to go balanced after all this but just saying. I think my best move is to simply polish my current build and call it a day. Some loctite and some feet should finish it.

Why oh why can't admins be put on ignore, sigh.

Good old kw at it again. Should have quoted the rest of the post where he pretty much disputes himself. Dampening factor can't do shit, but OTL is out, but Wa3 sounds good except that it affects the sound

My source's output is fully discrete differential drive. If you look at the circuit board you can see the four channels. That said they are all the same so the effective difference is CMR and output level. The headphone at this point looks more and more to be the LCD-2 which though not efficient is about as easy a load as they come. I certainly don't need more drive than I have now. Loud for me right now SE happens are about 9 o'clock. Think what it really comes down to is... do I keep my current clean but DIY 2ch single case b22 or snag the 3ch two box Rockhopper has up for grabs. Also messaged him about modding it to balanced but I think thats throwing money into a hole. I think I read KG was not a fan of 3ch builds and gave tech reasons but like AMB defense of balanced drive may not really mean anything in the real world in context of the b22. Certainly not about to ask thrice? to remove a board though

Thanks gents. The current case is the rackmount looking one n_maher uses. Brushed aluminum front, black painted sides and top. Might be black metal, I'm at work. Thinking plain jane black rubber or brushed aluminum ones. That said there are no holes for the feet and I'm not too keen on drilling into a completed amp Could probably use and adhesive to get the metal ones to stay in place. Rubber would be easier I think though since its solid and not a metal sleeve on rubber. Is getting loctite on the board anything to worry about? I'd like to just put a drop on the current layout without removing anything. When I opened my KGSS it looks like Justin does this at the end as jacks and even trim pots are dabbed with red loctite to keep them in place.

Lets try this another way. I'll answer the question, you guys correct me 1 v 2 boxes, the idea is to keep the transformer away from the amp board. Sounds reasonable but most commercial builders don't so is it because its not really a problem or is the added cost something that makes it less attractive for them. 2 v 3 channel, equal power, increased noise, reduced dampening factor, increased output impedance, drops noise on the line. My impression, more meh. The faults that would require the benefits likely don't exist in the real world and the downsides are kind of moot since noise, output impedance are so low to begin with so... meh. 2 v 4 channel, increased output impedance, increased noise, increased power and slew rate. More of the same negatives that don't add up to much and benefits that given the performance of the b22 seem to be adding a whole other level of overkill. That about right

The thunderpants even... zing Ok I'll stop now.

More details... My source is 1.4v SE, 2.8v balanced. Which is why I would set the gain to 2x balanced instead of 5x. Assume the output of the 2/3/4 channel amps is the same for this discussion.

I like comments like that, good for the wallet.

I currently have a 2ch build with a gain of 5 that I like so like all things we like I want to change it So what are the real world, measurable and not measurable differences in: 2 v 3 v 4 channel builds 1 v 2 case builds Assume single o22 for all three. Gain set so output would be similar. Same parts selection except the pot etc. Go!

My b22 has felt feet and is in dire need of something, anything better that will provide some lift. Also what version of loctite is safe to use on nuts, bolts, screws, pots inside the amp? Things were pretty loose when I got it and have been tightened but I'd like it to be a one time thing

Doesn't it though? I heard parts of the login sound that had been buried before, kudos to the MS audio engineer

Any easy way to shield the transformer? Rather not have to commission another one, though a 4ch once I find a dynamic worth the investment might be interesting Anyone know if Rockhopper, forget the members name, is ok with modding his already finished ones?

I'll be comparing my second LCD-2 pair to the O2. Hopefully fairs better than the first which I hope have a detached driver or some other major fault.

That is exactly what I'm referring to. So short answer is its wired with unshielded cable. Hmm odd that nothing else is picking it up.

I recently got a Nugget B22 that had been around so I gave it a good tightening and put it to work. Sounds great no issues there. However I have noticed that like the consumer PC speakers I have at work, it picks up Blackberry traffic and passes it through to the headphone. Has never happened to my KGSS in the four years I've had it. So the question. What causes that and is there any way to fix it?

Nah its the stock not Alo... zing The damage was to the R mount. Got over torqued and cracked from one side across then down. Also the cable's techflex doesn't quite reach the heat shrink Both really should have been noticed by the tech who assembled them. Now Audez'e is out a headband and cable and shipping to Canada because no one gave them a one over before packing them up. Sound wise there just seems so far to be an overall softening of the music. Very little attack and air.

Finally got mine complete with damage that occurred during assembly, yay. So far honestly not getting the hype. I'm going to use them exclusively this week before pitting them against the HE-5LE and O2 but not looking good on first listen.

No harm in trying. Worked for Monster with Dre and Gaga.

Now now Kevin, KW proclaimed the LCD-2 gods gift to audio and that the smaller the tube the more bass it produces

Throw everything out of whack? At best it increases supply power to the chips, likely increasing its bias into class A. At worst throws off calibrations and sends the chips into cascading spiral. Long and the short of it... if you aren't running out of power... don't overclock your amp =P

You remember when you got on the list?

Yet didn't even try to recommend me the WA2... hmmm. 7236 has 2W output into some mystery load though so thats good. The WA6SE I think is 1W into the HE-5LE.

When I polled Jack last week to find the differences in the product line about all I got out of it was... "The 5LE and the LCD-2 headphones are fairly low efficient. A high power output amp is highly recommended. With this end, the WA6-SE is a better match. The WA6 will not have enough power to drive these phones at comfortable volume." It was like pulling teeth to get that much and I don't think its even accurate since people are using the WA6 with the LCD-2 which only need 100mV to reach 90dB.

Me neither. Always had amps with outputs that were close to shorts.
